Develop, debug, and test your own M-file function to switch the rows of a matrix using a permutation matrix. The first lines of the function should be as follows:
function B = permut (A, r1, r2) SS% permut Switch rows of matrix A% with a permutation matrix% B = permut( A,rl,r2) SS% input% A = original matrix% r1, r2 = rows to be switched% output:% B = matrix with rows switched.
Include error traps for erroneous inputs (e.g., user specifies rows that exceed the dimensions of the original matrix)?
